Are you perhaps one of the people who still heat themselves with wood? Be aware that more and more individuals are using this means to cope with the cold of winter. It is both economical and ecological. However, not all types of wood are created equal. It is important to choose the quality of your wood for total optimization. But how do you know if the wood you bought to heat you this winter will perform well? Is it dry enough and will the variety of the tree allow you a good toast? Find all the answers to your questions here!
How to recognize a good wood?
You should know that 1 kg of wood provides 5 kWh of energy. The wood must be dry, that is, with a level of humidity below 20%. To go below the 20% humidity mark, the wood generally needs to dry for a period of 15 to 24 months depending on the place of drying and the thickness of the cut of the logs.
The best time to cut trees is in the fall and winter, when the trees are letting the sap down to the roots.
To choose the right firewood according to the different species available, you should know that at equal volume the calorific value is very different according to the species of wood. The choice therefore has an important role depending on what you want to heat.
The different types of wood species
The three species The main types of trees are the hard deciduous trees, the soft deciduous trees and finally the softwoods.
1) The hard deciduous trees are dense and slow growing. They provide a lot of heat and burn for a long time, but they are hard to crack and have a rather long drying time. Chestnut, hornbeam, oak, beech, ash, elm, walnut, locust as well as fruit trees are part of this tree species.
2) The second essence is soft leafy trees which are sparse. They have a medium heating power as well as a fast burning rate. This essence can be used to start a fire. They dry quite quickly compared to the first species, but generally keep less well. This species is made up of alder, birch, plane tree, willow or even poplar.
3) Finally, the last species is not very dense: these are softwoods. These are light and soft woods that heat quite well, but with a fairly rapid combustion. However, they produce embers that can shatter. And the resin contained in the wood tends to foul the chimney. The trees found in this species are spruce, fir, pine and larch.
In short, reliable firewood is dry, dense and hard. In addition, consider buying it before the end of the heating period in order to finish drying it at home and thus be able to find the wood a little less expensive. Don’t forget to heat the garden with mulch!
